We aren't really. We are guiding people to get college degrees. However, undergraduate education and professional research are both done by the same institution. Further, that institution likes to have those professional and apprentice professional researchers work as teachers. The result of this is that undergraduates get a lot of exposure to professional Academia, so they naturally have a tendency to develop an interest in that profession. Given how small the profession actually is, even a small tendency here saturates the job market.
